It's all kinda Voodoo Mojo, Black Magic.
You type stuff on your Computer and then (somehow) people See It and then they type stuff back. And the Crazy Part is, it is almost in Real Time.
So you might type...
"What's the Deal with the PG to VG Ratio in an e-liquid? And what should I go with if I want More Clouds?"
Then, Bingo-Bango, a bunch of People come along and start Explaining what PG and VG does, the Pro's and Con's, the Socially Economic Ramifications to Trade in a Tariff Free Market (well, yeah..., Not so much of stuff like that), and then many times ask you what you are Using now?
It's All pretty Darn Cool if you have Questions about e-Cigarettes or e-Liquids.
